Title: Improvements relating to gas purification
Inventor: GARDINER LESLIE ARTHUR JOHN
IPC: B01D53/02
Filed: 1958-01-20
Abstract: <PICT:0895486/III/1> Argon or helium is freed from hydrogen or oxygen by passage through an annular preheating zone surrounded by an electric heating coil enclosed in thermal insulating material followed by p  passage in the reverse direction through an inner chamber containing an absorbent.  Absorbents specified are copper oxide, tantalum, and zirconium for hydrogen and tantalum, zirconium, calcium, copper, and molybdenum for oxygen.  As shown, the gas to be purified follows a tortuous path through annular chambers 14 to 9 to inlets 6b of an annular chamber 2 surrounded by a coil 4 embedded in powdered refractory 5.  The gas then passes through annular chamber 2 in one direction and then via inlets 3b through an inner chamber 1 containing an absorbent in the reverse direction.  Instead of annular chambers 14 to 9, chamber 2 or a chamber surrounding it may contain longitudinal, radial, or helical baffles.  Chamber 1 contains a fine mesh gauze 36 at its inlet end and baffles and/or reflectors 27 at its outlet end and is surrounded by a cooling coil 26 at its outlet end.  The coil may be replaced by fins or a jacket.  The outlet tube 125 of chamber 1 is mounted on a removable end plate 28 having a sealing ring 31.  Powdered refractory 5 may be surrounded by a solid body of refractory itself surrounded by an annular metal chamber filled with small spherical bodies.

Title: Process for the production of iron oxide pigments
IPC: C09C1/24
Filed: 1939-01-19
Abstract: 505,425. Ferric oxide pigments. I: G. FARBENINDUSTRIE AKT.-GES. Jan. 19, 1939, No. 1954. Convention date, March 25, 1938. [Class 1 (iii)] Ferric oxide is dissolved in an alkali -metal borate melt and after cooling is separated therefrom for use as a pigment in paints and lacquers, this process converting the ferric oxide from rhombohedral crystals to crystalline flakes. For example, 30 parts by weight of ferric oxide are fuzed with 70 parts of anhydrous borax at 1000‹ C., then the melt is cooled at such a rate that it reaches 600‹ C., in about 1 to 1¢ hours. When cold, the mass is crushed and treated with 650 parts of 2-N-nitric acid which dissolves the borax and any residual dissolved ferric oxide. The flakes of ferric oxide are filtered off, washed and dried. The acid solution is evaporated to dryness, and the dried mass used again. The form size and shade of the flakes depend to a certain extent on the rate of cooling.

Title: Improvements in and relating to roller weirs
IPC: E02B7/36
Filed: 1928-01-27
Abstract: 290,543. Marks, E. C., R., (Maschinenfabrik Augsburg-N³rnberg Akt.-Ges.). Jan. 27, 1928. Movable weirs.-In a roller weir with a flap k which may be raised and lowered with respect to the weir, the flap is lowered bv the winding- gear before it operates to raise the weir. For this purpose the winding-gear is rotated as shown by the arrow, Fig. 1; the right-hand side of the chain b runs down, rotates the segments e, e<1>, and depresses the flaps k by means of the links g, g<1>, h, i. In the meantime the stop m on the chain will have moved from the abutment o to the abutment p, stopping the chain. To raise the roller, the run of the winding-gear is continued, so that the chain between the pinion a and the stop m is wound up on a suspension device q. During its rise the roller weir d, which runs on a rack z, turns and assumes the position shown in the upper part of Fig. 1, the segment e becomes disengaged from the chain, and the segment e<1> becomes engaged with it. A modification is shown in Fig. 3. If, when the weir has been lowered, it is desired to raise the flap k, the winding-gear a is rotated as shown by the arrow; the chain b' between it and the rolller d slackens, and a pulley t, to which is attached an auxiliary rope u, rotates so as to tighten the rope and to rotate a pulley w inside the roller weir d, and this to erect the flap k by means of the crank g<2> and rod i'. A second rope x attached to the pulley w will be kept under tension by the weight y, which will be raised, in readiness to operate so as to lower the flap k when, in order to lift the weir, the rotation of the winding-gear is reversed, and the pulley t rotates clockwise so as to slacken the rope u. Continued rotation of the winding-gear a lifts the weir, and the chain b<1> is stowed on the suspension device q, as in the modification described above.
